My search for an all around / SC gun has me currently looking at this model. My first question is why is it so much cheaper than a 400? My next question is, Beretta has a 30” barrel listed for this but I have had no luck finding one. And my last question is will this gun hold up like the 391 or 400? Or is that a completely stupid question. I was looking at the Rem 1100 but I’ve read way too many nightmares about them and that’s a shame because I really liked the one I handled. It was a new sporting model and $925 out the door.
